COPD exacerbations are a major cause of morbidity and mortality. Although inhaled corticosteroids (ICS) have a role as long-term treatment, their efficacy in exacerbations, particularly as an adjunct to systemic steroids, remains unclear. ⋯ Despite the known benefits of ICS in managing chronic COPD, we did not find an added value of ICS to systemic steroids in exacerbations. These results underscore the necessity for individualized treatment strategies and further research into the role of ICS in COPD exacerbations.

Randomized Controlled Trial
Direct Health Care Costs Associated With a Multicomponent COPD Exacerbation Intervention.
Health care costs attributed to COPD have been estimated at $4.7 trillion globally in the next 30 years. With the global burden of COPD rising, identification of interventions that might lead to health care cost savings is an imperative. Although many studies report the effect of COPD self-management interventions on subject outcomes and health care utilization, few data describe their effect on health care costs. ⋯ Controlling for important confounders, we found lower public community health care costs but no difference in acute health care costs with our multicomponent COPD exacerbation prevention management intervention compared to usual care. Community health care costs were almost double those incurred compared to acute health care costs. Given this finding, although most COPD exacerbation management interventions generally focus on reducing the use of acute care, interventions that enable health care cost savings in the community require further exploration.

Comparative Study
Lung Volume and Ventilation Distribution After Bariatric Surgery-High-Flow Nasal Cannula Versus CPAP.
Patients with obesity are at increased risk of postoperative pulmonary complications. CPAP has been used successfully to prevent and treat acute respiratory failure, but in many clinical scenarios, high-flow nasal cannula (HFNC) therapy is emerging as a possible alternative. We aimed to compare HFNC and CPAP in a sequential study measuring their effects on gas exchange, lung volumes, and gas distribution within the lungs measured through electrical impedance tomography (EIT). ⋯ HFNC at a flow of 100 L/min induced postoperative pulmonary recruitment in bariatric subjects, with no significant differences compared to 10 cm H2O CPAP in terms of lung recruitment and ventilation distribution.

Observational Study
Reducing Airway Occlusion Time Without Losing Accuracy to Predict Successful Mechanical Ventilator Liberation During the Measurement of the Timed Inspiratory Effort Index.
In 2013, a new predictor of successful mechanical ventilation liberation named timed inspiratory effort (TIE) index was devised with the normalization of the maximum inspiratory pressure (obtained within 60 s of unidirectional airway occlusion) with the time at which the value was reached. The aim of this study was to verify whether the presence of a sequence of a certain number of inspiratory effort values between 30-60 s > 1.0 cm H2O/s could predict weaning success in a performance comparable to the TIE index. ⋯ The presence of a sequence of ≤ 4 inspiratory efforts > 1.0 cm H2O/s during the TIE index measurement was a reliable predictor of weaning success, which could allow timely interruption of the procedure and entail a substantial reduction in airway occlusion time.

In recent years, acute lung injury (ALI) and ARDS have emerged as critical health concerns, drawing considerable attention from clinicians. The volume of published articles on ALI/ARDS is on the rise, indicating the expanding research interest in this field. However, the precise quantity and quality of studies on ALI/ARDS remain unclear. Consequently, we employed bibliometric and visual techniques to comprehensively analyze the patterns and focal points of these articles. ⋯ This study provides a historical perspective on the scientific advancements in ALI/ARDS research, highlighting the need for further investigation and development in specific areas within the field. Bibliometric analyses revealed that the United States is the predominant force in the field of ALI/ARDS, contributing significantly to its development. Through an examination of highly cited papers on ALI/ARDS, we have identified global research trends, assessed the quality of studies, and identified hot topics in the field of ALI/ARDS.
